It causes sufferers’ ability to walk, speak, swallow and breathe to severely deteriorate. Van der Westhuizen was one of South Africa’s finest rugby players. “Joost will be remembered as one of the greatest Springboks, not only of his generation, but of all time,” South Africa Rugby president Mark Alexander said. “He also became an inspiration and hero to many fellow sufferers of this terrible disease, as well as to those unaffected. “We all marveled at his bravery, his fortitude and his uncomplaining acceptance of this terrible burden. “It’s a sad day for rugby in South Africa, and across the globe, as we say goodbye to a legend of the Springboks. Our condolences go to his family and friends at this sad, sad time.” South Africa’s sports minister Fikile Mbalula said Van der Westhuizen’s contribution to the national team was “immense.” “He leaves behind a generation of athletes who aspire for his legendary sportsmanship,” Mbalula said in a statement. “We draw lessons from his fighting spirit.” Have your say on our Facebook page A scrumhalf, the father-of-two helped the Springboks win the World Cup for the first time.
